Abstract
The invention discloses an altitude lifting adjuster for a tractor. The altitude lifting adjuster comprises an air storage tank, altitude valves, conversion valves, electromagnetic altitude control valves and air springs. The air storage tank is connected with the altitude valves and the electromagnetic altitude control valves, the altitude valves are connected with the conversion valves, and the conversion valves are connected with the air springs. The altitude lifting adjuster for the tractor has the advantages that the altitude lifting adjuster is simple in structure and can be used and installed conveniently and quickly, and the altitude of the tractor can be automatically adjusted.
Description
Technical field
The present invention relates to a kind of height lifting device, more precisely a kind of tractor truck lift in height adjuster.
Background technology
As everyone knows, all tractor trucks on the market have headstock without compartment, generally when being connected with trailer, tractor truck need to be stepped back, by the height of manual regulation tractor truck, the final position that accurately snaps into trailer hinged disk, this method needs to attempt accurately snapping into position just now several times in the process connecting, and time-consumingly takes a lot of work again.
For these reasons, designing a kind of device that can automatically regulate tractor truck height is to be badly in need of a technical matters solving.
Summary of the invention
The present invention solves the existing technical matters of prior art, thereby provides a kind of simple in structure, a kind of tractor truck lift in height adjuster convenient to use.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of tractor truck lift in height adjuster, it comprises storage tank, levelling valve, change-over valve, electromagnetism height-control valve and air bellow, described storage tank is connected with electromagnetism height-control valve with levelling valve, described levelling valve is connected with change-over valve, described change-over valve is connected with air bellow, the two ends of described electromagnetism height controller are wound with respectively rising coil and reduce coil, and described change-over valve can be automatic switching valve or manual switching valve.
Therefore a kind of tractor truck of the present invention by the advantage of lift in height adjuster is, simple in structure, can automatically regulate tractor truck height, easy to install and use quick.
Accompanying drawing explanation
Fig. 1 is the gas circuit schematic diagram of lift in height adjuster for a kind of tractor truck of the present invention;
Wherein,
1, storage tank; 2, levelling valve;
3, change-over valve; 4, electromagnetism height-control valve; 5, air bellow
44, rising coil; 45, reduce coil.
The specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides a kind of simple in structurely, can automatically regulate tractor truck height, a kind of tractor truck lift in height adjuster convenient to use.
As shown in Figure 1, a kind of tractor truck lift in height adjuster, it it comprise storage tank 1, levelling valve 2, change-over valve 3, electromagnetism height-control valve 4 and air bellow 5, described storage tank 1 is connected with electromagnetism height-control valve 4 with levelling valve 2, described levelling valve 1 is connected with change-over valve 3, described change-over valve 3 is connected with air bellow 5, and the two ends of described electromagnetism height-control valve 4 are wound with respectively rising coil 44 and reduce coil 45, and described change-over valve 3 can be automatic switching valve or manual switching valve.
Described electromagnetism height-control valve 4 has electromagnetism height-control valve A and electromagnetism height-control valve B, electromagnetism height-control valve A and electromagnetism height-control valve B intercommunication.
Described change-over valve 3 comprises change-over valve A and change-over valve B, change-over valve A and change-over valve B intercommunication.
When tractor truck does not need to regulate height, levelling valve is connected with change-over valve, electromagnetism height-control valve is not worked, in the time the height of tractor truck need to being regulated, regulate change-over valve to be connected with electromagnetism height-control valve, by remote controller, connect the rising coil on electromagnetism height-control valve or reduce coil, thereby realizing the regulating effect of tractor truck height.
